General Description

The MAX5527/MAX5528/MAX5529 linear-taper digital potentiometers perform the same function as mechanical potentiometers, replacing the mechanics with a simple 2-wire up/down digital interface. These digital poten tiometers provide an optional one-time programmable feature that sets the power-on reset position of the wiper. Once the wiper position is programmed, the 2-wire inter face can be disabled to prevent unwanted adjustment.
